std::ranges::filter_view<V,Pred>::sentinel
class /*sentinel*/; |
(since C++20) |
The return type of filter_view::end when the underlying view type (V) does not model common_range.
The name sentinel is for exposition purposes only.
Data members
Typical implementations of sentinel hold only one non-static data member: the sentinel of the underlying view (shown here as end_ for exposition only).
Member functions
|
(constructor)
(C++20)
|
constructs a sentinel (public member function) |
|
base
(C++20)
|
returns the underlying sentinel (public member function) |
std::ranges::filter_view::sentinel::sentinel
/*sentinel*/() = default; |
(1) | (since C++20) |
constexpr explicit /*sentinel*/( filter_view& parent ); |
(2) | (since C++20) |
std::ranges::filter_view::sentinel::base
constexpr ranges::sentinel_t<V> base() const; |
(since C++20) |
Equivalent to return end_;.
Non-member functions
|
operator==
(C++20)
|
compares the underlying iterator and the underlying sentinel (function) |
operator==(std::ranges::filter_view::iterator, std::ranges::filter_view::sentinel)
friend constexpr bool operator==( const /*iterator*/& x,
const /*sentinel*/& y ); |
(since C++20) |
Equivalent to return x.current_ == y.end_;, where current_ is the underlying iterator wrapped in filter_view::iterator.
The != operator is synthesized from operator==.
This function is not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when std::ranges::filter_view::sentinel is an associated class of the arguments.
